Besides the principles, the nature of which has 
been just discussed, others have been described by 
chemists as belonging to the vegetable kingdom : 
thus a substance, somewhat analogous to the mus- 
cular fibre of animals, has been detected by Vau- 
quelin in the papaw ; and a matter similar to ani- 
mal gelatine, by Braconot, in the mushroom ; 
ulmin and emetine, sarcocol, nicotine, olivile, 
asparagine, inulin, and other bodies, are generally 
described in systematic writers in chemistry as spe- 
cific compounds ; but it is likely that few of these 
bodies will retain their places as definite combin- 
ations : their existence, likewise, is extremely
